"We were hanging out in September and I said, 'Bethany, is there anything you can't do? I've been thinking about this,' " Scruggs tells PEOPLE. "And she's like, 'No, actually not.' It's pretty amazing."

Hamilton has also taught her new friend some everyday adaptations. "Bethany actually showed me how she just rolls her hair up in a bun and clips it, which I do sometimes," says Scruggs.

But the lessons she's learned from her Hamilton go far beyond the physical. "She's still a pro surfer and she has one arm – she's not letting her accident deter her from doing what she loves," says the fashion blogger, who details the accident and its aftermath in this week's PEOPLE magazine. "That's a big lesson I've learned, not letting fear or insecurity bring you down."

"Bethany and I even talk about doing some things together with people who've lost limbs," she adds.

Robin Roberts Sends Her Best

Good Morning America anchor Robin Roberts has been going through a public health battle of her own, so Scruggs says she was particularly touched when Roberts reached out to her.

"Robin would send us really encouraging emails and Bible verses – things she's held onto in her life, like faith and family," says Scruggs, who says her Christian faith has helped her in the aftermath of what she's been through.
